How to partition your SD card?

From dual booting Android on Windows Mobile OS device to install dark tremor’s a2sd, you may across various situations where you will require your sd card to be partitioned. There are numerous methods to do the same. Some require you to play with console and custom recoveries while other will require you to boot from an Ubuntu live cd. But here are 2 of the simplest & noob-friendly methods you can find over the internet to partition your sd card.

Reminder: Partitioning will wipe all data from your SD card. So take a back up of  your data first.

Method 1: ClockworkMod Recovery

  1. Reboot into Clockworkmod recovery.
  2. In CWM, advanced-> partition SD card.
  3. Once the option is selected, you will be given options to choose the sizes for the sd-ext partition as 128,256,512,1024, 2048 ans so on. This will be the size of your first partition where apps are moved using a2sd,link2sd etc.
  4. Now you will be given the option to select size of an optional /swap partition on the SD card. If you don’t want a swap partition then select 0.
  5. The remaining space will be used for normal SD card usage. When you press ok, the recovery will do the rest for you. It may take a little time so be patient.

If you don’t have a custom recovery installed, even then you can partition your sd card very easily.

Method 2: MiniTool partition

  1. Download MiniTool Partition & install it on your windows machine.
    Note: As a word of caution, create the partitions in a fixed sequence. Don’t skip the cycle and create the other two partitions first. For some reason if you already have partitions in your SD card, delete all your partitions in the SD card until the whole SD card is a single partition on it’s own.
  2. Using this partitioning free software, right click on the SD card’s partition and select “Resize”. Drag the slider to resize your partition to your desired value.

  3. Create an Ext2 partition (Or ext3/ext4)
    Right click on the remaining space in the SD card and create an Ext 2 partition . Choose a value that you find comfortable, depending on your size of your SD card.

  4. Create a Linux Swap file

  5. Finally, click on the “Apply” icon at the top left hand and allow the system to make the necessary changes.

  3. I was suggested this blog through my cousin. I’m no longer positive whether this submit is written via him as nobody else know
    such specific about my difficulty. You’re incredible!
    Thank you!

  4. still my internal memory using while installing apps..the newly partitioned space remains same,no application can move to that while using link to sd also…anyone have the solution…still it doesn’t showing increased memory in task manager..so whats the use of this ? 😮

  5. @Devesh and anyone else with the same problem:
    I had the same issue, after hours of brain storming, I finally figured it out:
    Instead of doing the whole thing in one go, try breaking it down into smaller processes,
    i.e.
    First, create the partition and press apply,
    Then, create ext2 and press apply.

    @chethan:
    I would suggest the second method,
    Why?
    1) The first method required you to flash your phone with CWM (incase you dont have it)
    2) A video tutorial on youtube about partitioning sd card using the second method said that it is crucial that you connect your sd card to your computer via an adapter NOT by wire (data storage mode) because otherwise the partitioning process will fry your card… notice that method 1 involves partitioning while the sd card is in your phone, i assume the same idea applies here as well…. i cant understand the logic behind this but i’d rather be safe than sorry.
    3) I never really liked playing around with my phone in recovery mode… too much fragile data.
    4) I successfully partitioned my sd card using the second method.

  6. I am getting error while partitioning my New Transcend 8 GB class 10 SD card through Mini Tool.
    It says Error 16 Data I/o Error. Please Help I am stuck
